Patented Oct. 31, 1916.

Original application iiled npril 10, 1915, Serial No. 20,478. Divided and this application filed October 27,

1915. Serial No. 58,212.

To all whom it may concern:

Beit lmown that I, ALFRED CARLSON, a citizen of the United States, residing at Klamath Falls, in the county of Klamath and State of Oregon, have invented certain new and useful Improvements in Gearing, of which the following is a specification.

This invention relates to improvements in driving mechanisms adapted for converting rotary into reciprocatory motion of the type disclosed in my co-pending application Serial Number 20,473, filed April 10, 1915, of which this case is a'division.

Among other objects in view the device is designed to provide a compact system of gearing capable of being inclosed within a housing or casing so as to operate in a lubri cant bath, provision being made for efi'ectively preventing the escape or loss of the lubricant by so arranging the parts as to' preclude injury owing to this cause. It is comprehended, furthermore, to so construct the mechanism as to obtain a maximum throw of the reciprocated member, which is a desideratum in constructions of this type.

These and such other objects as may hereinafter appear are attained by the novel. con

struction, combination and arrangement .of-

parts to be hereinafter specifically described and claimed.

Reference will now be had to the accompanying drawings forming a part of this specification, wherein Figure 1 is a vertical sectional view through an embodiment of this invention; Fig. 2 is a similar section taken about on the plane indicated by the line 2-2 of Fig. 1; Fig. 3 is a vertical sectional view through a modified form of the apparatus; Fig. 4 is a vertical section on the line 4-4 of Fig. 3; Fig. 5 is a view. in elevation, partly broken away and shown in section, showing an embodiment of the invention diflering from the construction disclosed in Fig. 1 only in respect to its connection with the reciprocatory member; Fig. 6 is a vertical section on the line 66 of Fig. 5; Figs. 7 and 8 are horizontal sectional views taken on the lines 7-7, and 88 of Figs. 5 and 6, respectively; and Fig. 9 is a detail perspective view of the detachable connection intermediate the reciprocatory member and its actuating gear element.

Throughout the following detail description and on the several figures of the drawings, similarparts are referred to by like reference characters.

Specifically describing my invention and referring particularly to Figs. 1 and 2, the numeral 1 designates a casing of a suitable form and size to house thetransmission gear-- trally thereof. A suitable bearing collar 7' .is interposed between the interior wall of the hub and the extension 3 for facilitating r0.- tation of the wind wheel, said wheel being connectedthrough its hub to the end of a drive shaft 8 revolubly mounted within a longitudinal bore of the extension 3. The inner side of the hub 5 is formed with a brake flange or drum 9 through which the rotation of the driving element may be controlled where the mechanism is adapted for windmills.

The inner end of the shaft 8 extends intothe hollow portion of the casing 1, which it may be here stated is adapted to contain a lubricant, and keyed or otherwise secured to the shaft is the driving pinion 10 meshing with a spur gear 11 loosely carried by the supporting shaft 12, in turn secured to the supporting member or arm 13 loosely mounted upon the drive shaft '8 intermediate the pinion 10 and the rear wall of the casing 1, said armhaving a-hub 13' journaled in said *casing. The opposite end of the shaft 12 has loosely mounted thereupon a large spur gear 14 which is made fast to thegear 11in any desired manner, as by means of the fastening members or bolts 15. The gear 14 intermeshes with the internal gear teeth 16 formed a:mularly about the inner wall of the cas- Tt will be obvious from the foregoing description that the gears 11 and l lhav'e plan- 'etary movement about the driving. pinion 10 on the shaft 8, and said gears may be arranged with any desired ratio depending upon the power required for the work to be accomplished. The gear 14 is provided with a detachable crank pin 17 to which is connected the pitman 18. cooperating with a vertical groove 19 formed in the cover2. By this construction and arrangement of parts the pitman just mentioned is operated in a direct vertical path which is one of the particular features of my invention. I also lay stress upon the fact that the casing 1 is of a character to hold a suflicient supply of lubricant whereby the gears operate substantially noiselessly and with a minimum amount of wear. The casing 1 is formed with a duct 20 for feeding the lubricant to the shaft 8. The pitman 18 is surrounded with a packing 21 held in place by the gland 22 screwed into the base of the casing 1 which is mounted upon the turn table 23 of a wind mill or other support according to adaptation of the driving mechanism hereinbefore set forth.

Owing to the fact that in this type of construction of the mechanism as above described it is requisite that the packing 21 be held in place and the wear thereon taken up from time to time, it is sometimes a disadvantage since unless'these precautions are taken the lubricant is likely to escape from the casing and cause unnecessary wear and vinjury to the gear elements. To eliminate the wear and adjustment, therefore, I have devised a slightly different arrangement which is shown most clearly in Figs. 5 and 6 of the drawings. In thisconstruction the gear members and elements maintain their relative position and perform their identical functions-as the equivalent elements in the form first described. However, instead of connecting the gear member 14 directly to the reciprocatory member, which may be any pitman connection or which is the pump rod in the construction of a wind mill, the detachable crank pin 17 is connected to the lower end of a rod 24 which extends upwardly and into the superposed casing extension 1 detachably connected to the easmg 1 as indicated at 25. The upper end of the rod 24 is connected by means of the pins 26 to the upper end of the reciprocatory member 18. This rod extends downwardly through the support for the casing and is held in place by means of the cover 2 pro-. vlded for the casing 1. This cover consti tutes guide means both for the rod 24 and the reciprocatory member 18, as will be observed most clearly by reference to Fig. 8 of the drawings. The cover 2 is preferably hingedly connected to the casing at 27 and there is provideda removable cap 2 which is attached to the outer face of the cover and extends over the casing extension 1. It may be stated at this point that to disconnect the reciprocatory member for the purpose of opening the cover 2 for access to the internal gears, it is contemplated In this form it will be obvious that no packing is required for the pump rod or reciprocatory member 18, and escape of the oil from the casing 1 is quite adequately prevented.

In Figs. 3 and 4 is disclosed a modified form of this invention designed with a view to obtaining a maximum thrust for the reciprocatory member. The parts of this construction are also identical with those of the type shown in Fig. 1, excepting that instead of connecting the detachable crank pin 17 directly to the reciprocatory member said crank pin is provided with a rack pinion 28, said pinion meshing at one side with a rack 29 formed upon the cover 30 provided for the casing of this device. This rack constitutes a stationary element and during rotation of the planetary gear member 1 around its internal gear path the pinion 28 is caused to travel upwardly of the rack 29. The reciprocatory member 18' for this type of construction is provided at its upper end with a rack section 18" intermeshing with the rack'pinion 28 aforesaid at the opposite side of the rack 29. The rack section 18" coacts with a guide projection 31 on the cover so that it is mamtained in vertical line during reciprocatory movement under the actuation of the rack willalso be obvious to those skilled in the art to which the invention refers.

Having thus described the invention, what .is claimed is 1.
